Overview
Medicines or fluids may be given through an intravenous (I.V.) tube inserted into a vein. The I.V. is most often placed in the back of the hand, on the forearm, or on the inside of the elbow.
When the I.V. is in place, medicines or fluids can go quickly into the bloodstream and into the rest of the body. The I.V. can also be used to take blood for testing.
If you had an I.V. while you were in the hospital, the area where it went into your body may be tender for a while.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
